GE IS200ERSCG1AAA Exciter Regulator Static Converter Card

Description

IS200ERSCG1AAA Exciter Regulator Static Converter Card
Description:
IS200ERSCG1AAA is part of GE EX2100 series Exciter Regulator Converter Card.
The IS200ERSCG1AAA ERSC board provides the pulse width modulated (PWM) dc output current and the field discharge function for the regulator control. These two functions are defined as the power conversion module (PCM).
The PCM consists of an integrated IGBT inverter module that contains six IGBTs connected in a 3-phase inverter configuration. Two of the six IGBTs are used to cre-ate the PWM dc output for field excitation. A third IGBT is used to discharge the dc link capacitors into an external dynamic discharge (DD) resistor. Maximum output is 20 A dc continuous, 30 A dc for 10 seconds. Input power is either rectified ac, dc from a station battery, or both.
A relay, K3, is provided to bypass the dc link charging resistor. The dc link charging resistor provides a soft charge on initial power up for the dc link capacitors.
The EX2100 Excitation Control System is GE’s latest state-of-the-art control offering for both new and retrofit steam, gas, or hydro generation. GE has supplied morethan 6,000 full static and regulator systems in over 70 countries during the last 40 years. EX2100 is GE’s third generation digital excitation control system. There are over 1,000 first and second-generation GE digital excitation controls operating in 27countries. Hardware and software design is closely coordinated between GE’s sys-tem engineering and controls engineering to ensure delivery of a true system

solution. Integration between EX2100, Mark VI, Mark VI Integrated Control System(ICS), LS2100 Static Starter, and human-machine interface (HMI) is seamless. Forstand-alone retrofit applications, integration with customer distributed control systems (DCS) through serial or Ethernet ModBus is supported.
